NAME              du -- summarize disk usage

SYNOPSIS          du    [--s] [--a] [name...]

DESCRIPTION       du gives the number of blocks contained in all
                  files and (recursively) directories within each
                  specified directory or file name. If name is missing, "."
                  is used.

                  The optional argument --s causes only the grand total to be
                  given. The optional argument --a causes an entry to be
                  generated for each file. Absence of either causes an entry
                  to be generated for each directory only.

                  A file which has two links to it is only counted once.

DIAGNOSTICS

BUGS              Files at the top level (not under --a option) are not
                  listed.

                  Removable file systems do not work correctly since i--
                  numbers may be repeated while the corresponding files are
                  distinct. Du should maintain an i--number list per root
                  directory encountered.
